Management of sustainability

Materiality analysis (Material issues)

In order to contribute to the resolution of social issues through our business activities, we conducted a new analysis from the perspective of double materiality and identified particularly important challenges. Our aim is to achieve sustainable growth through a positive cycle of social issue solutions and improving profitability by incorporating materialities into our most important activities.

Risk management

The management principle of Komatsu is to maximize its corporate value through the commitment to “Quality and Reliability”. Any uncertainty that hinders this pursuit is considered a “risk,” and measures are taken to address all risks threatening the sustainable development of the Komatsu Group. In FY2024, risks and opportunities were identified and evaluated based on changes in the business environment, reflecting the materiality analysis conducted during the formulation of the new mid-term management plan (2025–2027).
